Having walked out on Boca Juniors in July and turned them down last month despite the return of record title-winning coach Carlos Bianchi, Riquelme has hinted he might want to wear their colours again after all.
Media reports said the club would announce on Friday if the former Argentina midfielder was going back but some board members seem unconvinced it is a good idea.
"Everything will be decided at a board meeting," Boca's general secretary Cesar Martucci told the sports daily Ole.
"When we're all together with our colleagues on the board, we'll settle [this]," he added, explaining the delay was due to club president Daniel Angerlici's business trip to Qatar.
Arch rivals River Plate, who have talented teenager Juan 'Mini Messi' Iturbe on loan for six months from Porto, travel to Cordoba on Sunday to face Belgrano, the side that relegated them in 2011.
Velez Sarsfield, who won the 'Inicial' tournament in the first half of the season, open their title defence at Argentinos Juniors at the Diego Armando Maradona Stadium on Friday.
There are mixed prospects for the big teams, arch rivals Racing Club and relegation-haunted Independiente from the Buenos Aires suburb of Avellaneda and Juan Antonio Pizzi's San Lorenzo.
Racing, who had a good run-in to the 'Inicial' with a talented young attack, have gone for experience in the transfer market by taking Argentina midfielder Mario Bolatti on loan from Internacional of Brazil.
Independiente are struggling in the bottom three of the relegation standings, a separate table calculated on average points over three seasons, and will need a good run in the 'Final' to avoid the drop for the first time.
They have brought back former Argentina midfielder Daniel 'Rolfi' Montenegro from Mexico's America and signed Colombian forward Jorge Caicedo.
